Antonio Carraro launched its first hybrid tractor in 2021, working with Ecothea, a specialist start-up at the Polytechnic of Turin.
Based on the company’s reverse drive, articulated models, the SRX Hybrid has a 55kW three-cylinder 1861cc engine, combined with a 20kW electric motor, for a total of 75kW, equivalent to 102hp. It can operate in full electric mode in closed environments such as glasshouses.
The structure of the hybrid-electric system makes it possible to exploit the available power of a diesel engine combined with an electric drive system, guaranteeing continuous traction when working with the PTO, during transportation and in material handling works.
Interaction between the diesel and electric traction motor-generator drive systems is managed by an electronic power control developed specifically for this type of machine.
When working in full electric mode, the battery pack is recharged each time the brakes are applied or via an electric charging station or the diesel engine.
The company has now developed a fully-electric tractor based on its proven SuperPark 4800 models, also in conjunction with Ecothea. Known as eSP, it has a 25kW, (33.5hp) engine, with 32kWh capacity battery packs operating at a high voltage of 640V to give up to six hours runtime, with the possibility of recharging it from the mains or from charging columns using a Cat 2 connection.
It features a hydrostatic transmission with electro-hydraulic control offering three speed ranges up to 30kph, cruise control and differential lock.
The choice of the AC SuperPark model, (hence the name eSP), targets the vehicle at grounds maintenance work, making use of the articulated ACTIO chassis to work in confined spaces and undulating surfaces.
The eSP has lift capacity of 1100kg on the front linkage and can fit attachments to its rear platform; it also offers two hydraulic spools to the front and one to the rear.
With the increased interest in low carbon fuels, Iseki has approved the use of HVO (hydrotreated vegetable oil) in the following tractor model ranges TG, TH and TLE. HVO is a fossil-free alternative to mineral oil, but with similar chemical and physical properties to diesel fuel whilst delivering lower NOx and particulate emissions. Further benefits over biodiesel include not being hydroscopic, nor prone to bacterial growth. A conversion kit for the TXGS24 subcompact model will be released later in the year.
